Application of Cooling Equipment Units in the Plastic-Wood Industry

Background of Application

In the plastic-wood composites (PWC) industry, cooling equipment units are critical for ensuring product quality, improving production efficiency, and reducing energy consumption. After high-temperature extrusion or injection molding, plastic-wood materials require rapid and uniform cooling to prevent deformation, cracking, or surface defects. Cooling equipment enables precise temperature control and efficient heat dissipation, ensuring dimensional stability, mechanical strength, and surface finish of products while supporting continuous production.

Key Application Scenarios

1. Extrusion Molding Cooling: Molten plastic-wood composites extruded through molds are rapidly solidified via water or air cooling systems to prevent warping or shrinkage caused by uneven cooling.

2. Mold Temperature Control: Cooling channels in injection molds work with external cooling units to shorten cycle times and minimize internal stress, enhancing product impact resistance.

3. Post-Surface Treatment Cooling: After processes like embossing or laminating, cooling equipment stabilizes material temperature to prevent texture distortion or coating delamination.

4. Recycled Material Cooling: During recycling of waste plastic-wood, cooling systems suppress thermal degradation to maintain the physical properties of regenerated materials.

Key Advantages

1. Higher Product Yield: Uniform cooling reduces defects like warping or air pockets, ensuring dimensional accuracy.

2. Energy Efficiency: Variable-frequency technology adjusts cooling intensity based on demand, lowering electricity and water consumption.

3. Extended Mold Lifespan: Prevents mold cracking or wear caused by thermal fatigue.

4. Eco-Friendly Design: Closed-loop water cooling systems minimize wastewater discharge, aligning with sustainable production standards.
